Increased Nitrite values can show the necessity to optimize the biological processes in wastewater treatment plants.
With the new WTW optical sensor NitraVis 700 IQ NI, Nitrite and Nitrate can be measured simultaneously, without any chemicals and directly in the process. This allows a complete and easy optimisation and a monitoring of the aeration.
Thanks to the unique integrated ultrasonic cleaning system of the opical window, maintenance is reduced to a minimum (see photo series).
For extreme duration, even in corrosive media, the sensor is made of Titanium and PEEK.
